In a wind power system, transformers are responsible for stepping up the turbine output voltage and transmitting electricity through the wind farm collection network. In 33kV, 35kV, and 38.5kV<\/a> collection systems, an incorrectly selected transformer may cause excessive temperature rise, increased noise, higher power losses, shortened insulation life, and unstable grid connection.<\/p>\n\n\n\n

Many buyers request quotations by providing only the wind turbine rating and a simple requirement such as \u201cone 35kV transformer.\u201d However, this information is not enough for accurate transformer design and pricing.<\/p>\n\n\n\n

For wind power applications, buyers must also consider the turbine output current, voltage level, vector group, short-circuit impedance, harmonic loads, cooling method, installation environment, insulation level, and applicable electrical standards.<\/p>\n\n\n\n

This article explains how to select a 33\u201338.5kV dry-type transformer for a wind power project and highlights several hidden issues that are often ignored during procurement.<\/p>\n\n\n\n
